Abstract
The contribution of the ‘‘gravitomagnetic’’ interaction to a well-measured perturbation term in the orbits of Earth satellites is calculated. Laser-ranging determination of the Moon’s orbit and Lageos-satellite orbit require the precise participation of the gravitomagnetic interaction; otherwise anomalous orbital perturbations exist. For the Lageos-satellite orbit, the gravitomagnetic interaction’s contribution to the orbit is a 100-m altitude variation of frequency ω-Ω (ω and Ω are satellite and Earth orbital angular frequencies, respectively), but which is nullified by effects from other well established post-Newtonian gravitational potentials.Keywords
